CHARACTERISTICS: Small, gram-negative, motile rods with polar flagella
SECTION II – HEALTH HAZARD
PATHOGENICITY: Characterized by two different clinical forms: a febrile anemia (Oroya fever) manifested by irregular fever, severe anemia, generalized lymphadenopathy and delirium; a dermal eruption (Verruga peruana) of small, hemangioma-like nodules with muscle and joint pain, and may be preceded by Oroya fever; fatality rate ranges from 10- 90% for untreated Oroya fever
EPIDEMIOLOGY: Limited to mountain valleys of Peru, Ecuador, and Southwest Columbia where the sandfly vector is present
HOST RANGE: Humans
INFECTIOUS DOSE: Not known
MODE OF TRANSMISSION: By the bite of sandflies (Lutzomyia); blood transfusion
INCUBATION PERIOD: Usually 16 to 22 days, occasionally 3 to 4 months
COMMUNICABILITY: Person to person transmission not documented; patient’s blood remains infectious for sandfly months after illness
SECTION III – DISSEMINATION
RESERVOIR: Humans
ZOONOSIS: None
VECTORS: Sandfly (Lutzomyia)
SECTION IV – VIABILITY
DRUG SUSCEPTIBILITY: Susceptible to penicillin, streptomycin, chloramphenicol, tetracycline
DRUG RESISTANCE: Nalidixic acid; in vitro resistance to penicillin and ampicillin, tetracycline and vancomycin has been noted
SUSCEPTIBILITY TO DISINFECTANTS: Susceptible to common disinfectants: 70% ethanol, 1% sodium hypochlorite, 2% formaldehyde
PHYSICAL INACTIVATION: Sensitive to heating
SURVIVAL OUTSIDE HOST: Survives in tap water at room temperature for up to 7 days
SECTION V – MEDICAL
SURVEILLANCE: Monitor for symptoms; demonstration of organism in blood or skin lesions
FIRST AID/TREATMENT: Antibiotic therapy
IMMUNIZATION: None available
PROPHYLAXIS: None available
SECTION VI – LABORATORY HAZARDS
LABORATORY-ACQUIRED INFECTIONS: One case reported up to 1988
SOURCES/SPECIMENS: Blood, skin lesion
PRIMARY HAZARDS: Accidental parenteral inoculation; contact with infected laboratory sandflies
SPECIAL HAZARDS: None
SECTION VII – RECOMMENDED PRECAUTIONS
CONTAINMENT REQUIREMENTS: Biosafety level 2 practices and containment facilities for activities involving known or potentially infectious materials
PROTECTIVE CLOTHING: Laboratory coat and gloves when working with infectious materials
OTHER PRECAUTIONS: Avoid accidental inoculation and follow general needle safety practices
SECTION VIII – HANDLING INFORMATION
SPILLS: Allow aerosols to settle; wearing protective clothing, gently cover spill with absorbent paper towel and apply 1% sodium hypochlorite starting at the perimeter and working towards the centre; allow sufficient contact time (30 min) before clean up
DISPOSAL: Decontaminate all wastes before disposal; steam sterilization, chemical disinfection, incineration
STORAGE: In sealed containers that are appropriately labelled
